CHARLES r. l AIGE, or DENVER, COLORADO.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 470,167, dated March 1,1892.

Application filed May 19. 1891.

To all whom it may concern:

Be it known that I, CHARLES l PAIGE, a citi-" zen of the United Statesof America, residing at Denver, in the county of Arapahoc and State ofColorado, have invented certain new and useful Improvements in Refrigeratms; and I.

vent the accumulation of ice or frost .upon the pipes through which thecooling-liquid is forced. These pipes being cooled below thefreezing-point, the surrounding moisture naturally collects thereon in acongealed or solidi-v fied. form. As this incrustation thickens, a

blanket, so to speak, is formed around the pipes, rendering thempractically useless for refrigerating purposes.

In my improved construction the uppermost pipe is perforated andcontains salt-wa-.

ter or other suitable liquid under pressure. The pipes below theperforated pipe are so arranged and supported in connection withdrip-brackets that as the liquid passes from the perforated pipe itdrips over the whole series of pipes in succession and finally passesinto a. trough at the bottom of the series,

whence it is conducted to anv suitable receprefrigerator.

My-improvcd construction will be fully understood by reference to theaccompanying drawings, wherein is illustrated an embodiment of myinvention.

In the drawings, Figure 1 is a vertical section taken through the upperportion of the Fig. 2 is a similar view of a. modified form ofconstruction. Fig. 3 is a fragmentary view, taken on an enlarged scale,of the mechanism shown in Fig. 1. Fig. 4'isa longitudinal section takenon thelinewm, hig.

1, the pipes being shown in elevation.

In the views, wherein similar reference characters designatecorresponding parts of the mechanism, let the numeral designate theouter walls of the refrigerator, which are constructed in the usual.way. Within these Serial No. 393,343. No model.)

walls and in the upper portion of the chamber are located the interiorwalls 15, forming a.double-inclined flue or air-conduit 20, the innerwall of which forms an apex at the top, The conduit opens at bothextremities into the'chamber below,thus giving a free circulation forthe air from chamber 25 through the flue 20 and'back again to thechamber.

In order to increase the cooling-s11 rface over which the air passes, itis preferable to arrange the cooling pipes on an inclined plane formedby one side of the inner wall 15,

to which are secured brackets 35, composed of a suitable seatgtO, uponwhich the pipe 30 rests, and an inclined drip-plate above this seat andterminating, preferably, directly above the center of the pipe, the seatand the drip-plate being connected by the web '50 of the b racket,through which portion thebracket is bolted or otherwise suitably securedto the wall 15, asshown.

The perforated pipe is located and suitably secured above the inclinedseries of cooling-pipes. Above this perforated pipe and almost "incontact therewith is a plate 60, having downwardly-inchned sides adaptedto throw the liquid issuing from the pipe back on itself and thence tothe first pipe 30 of the inclined series below, whence it is guided bythe first drlp-plate to the next pipe of the se-" ries, and so on to thelast, whence it passes to a trough 65.

' Another arrangement of pipes and dripplatcs is shown in Fig. 2.cooling-pipes 30 are arranged in two vertical air-flue 70, connectedwith lines 75, leading from the main chamber 25. The pipes 30 in thismodified form are supported by brackpts- 80, secured to the walls of theair-flue.

In this figure the series on opposite sides of a central vertical theopposite side of the flue from each pipe 30 and somewhat higher than thepipe is socured a downwardly-inclined drip-plate 85, provided with. asuitable supporting-brace. The perforated pipe 55 is supported above thevertical air-flue 70, so that the liquid escapin g therefrom shall fallon the first drip-plate 85, whence it is conducted to the pipe 30 on theopposite wall of the air-flue, and from this pipe to the next drip-platebelow, and so on until the lowest pipe is reached, when this liquid isconducted into a trough 90. It will thus be observed that by this simpleconstruotion salt-water or other suitable liquid may be dripped over thepipes continually, whereby the usual incrustation resulting fromcongealed moisture is obviated, while the increased cooling-surfaceaflorded by the dripplates is an important feature.

It may be well to state that all parts of the mechanism exposed tomoisture or liquid should be constructed of some non-corrodible metal,as galvanized iron.

Having thus (1 ribed my invention,what

1 claim is- 1. In a refrigerator, the combination of a seriesof'oooling-pipes arranged in the upper portion thereof, of a perforatednon-congealable liqnid-containin g drip-pipe located above thecooling-pipes, and downwardly-inclined drip-plates secured to the wallssupporting the pipes and so arranged with reference to the pipes thatthe liquid from the drip-pipe is conducted successively to thecooling-pipes of the series, substantially as and for the purposesctforth. a

2. In a refrigerator, the combination, with the cooli ngpipes, ofbrackets, each consisting of a seat and a downwardly-inclined drip'plate above said seat, and a non-congealable liquid-supplysource-located above the brackets, the brackets being so arrauged thatthe liquid falling from'said source is conducted v to the cooling-pipessuccessiyely, substantially as and for the purpose set forth.

In testimony whereof I afiix my signaturein presence of two witnesses.Cl IARLES l PAIGE.
